Comment: Karst Topography

(See in situ)


Karst Topography

It's karst topography. You'll see sinkholes in places like Texas and Florida because of the geology. There is a layer of limestone below the surface. The limestone reacts to elements carried into the ground by water. As the limestone deteriorates, it's possible to have sinkholes. I could be wrong, but I work in the oilfield and I'm almost definitely sure there is no man-induced hydraulic fracturing in Florida. Especially in Tampa.
